Adla and Badla Push Duggal

Overview

Chandramukhi arranges a swing to be able to deduce the identity of the person who pushes Duggal from the swing to reveal themselves, by analysing the impact, force and the touch of said person. She asks Duggal to swing, and tells Adla and Badla to push him one by one. But Duggal says that it is neither of them. What will Chandramukhi do now?
